DURING the progress of the work of Coster and Hevesy on the concentration and isolation of the new element hafnium (atomic number 72), the discovery of which was announced in NATURE of January 20, p.

Hevesy of Copenhagen, and named by them hafnium, was doubtless similar in ... first detected the existence of the element now known as titanium.

New connections discovered between the Sun's photosphere and CI chondrites meteorites, providing clues about the origin of materials.

Iron-hosted, zircon-rich zones containing hafnium are visibly present at Jokikangas. These zones have been defined but the drill core remains largely unsampled for these critical elements.

Space is a challenging environment for semiconductors, but researchers have shown that a specific type of memristor (the hafnium oxide memristor, to be exact) actually reacts quite usefully when ...
